What are the routines for playing Rubik's Cube?

Traditional Rubik's Cube, 3*3*3, 6-sided cube. The most basic way to play the Rubik's Cube is to restore the disturbed squares to the results of six-sided monochrome. Term: face: it is the six faces of the Rubik's cube. Each surface is composed of 9 color blocks, forming a well shape, such as:+-+-| |+-+| B | A |+-+| C |. Face: A face of the Rubik's Cube (regardless of color), that is, a group of nine small squares on a plane. Edge: The set of four edges of a surface. Angle: The set of four vertex angles of a surface. Stop: that is, the stop fixed on both sides. (A in the figure) Side block: that is, the block in the middle of three blocks where two faces intersect (B in the figure). The edge block has the color of two faces. * * * has 12 edges in total. Corner block: that is, the block at the vertex position where three faces intersect (C in the figure). The corner block has three colors. There are eight angles in all. Layer: Put the Rubik's Cube on the desktop. The Rubik's Cube can be divided into three layers from bottom to top. The second layer is a strip, and the first and third layers are complete faces with a circle of angles. Orientation: front, back, left, right, up and down: face one side of the Rubik's cube to yourself. Hold the sides gently with your left and right hands. The face facing you is called the front, the left hand side is left, the lower layer is down, the right hand side is right, the upper layer is up, and the invisible side parallel to the front is the back. Orientation is relative. Rotation: represented by three symbols,+,-and 2,+means 90 degrees clockwise,-means 90 degrees counterclockwise, and 2 means clockwise or counterclockwise 180 degrees. To restore the Rubik's cube to six sides, I usually use the "layered method", that is, the color of the Rubik's cube is adjusted layer by layer (called "reduction"), the first layer is adjusted, then the second layer is adjusted, and then the third layer is adjusted. For convenience, we label the number of layers of the Rubik's Cube as 1, 2, 3 from top to bottom. The first floor repair is divided into two steps: the first floor top surface repair and the corner block adjustment. Generally speaking, there is no fixed method to restore the top surface. Pay attention to the color adjustment according to the color of the top block, and try not to move the blocks that have been put in place. Basic principle: Edge blocks take precedence over corner blocks, and edges are restored one by one. The rate of using sulfuric acid to quench thirst was 23.9%: 2008-10-2417: 47. Maybe you can find the answer on this website:/mofang/zhang1-yi4/mofang1.php or. It's not just videos that teach you to play CFOP, but also sounds and videos. The explanation is very detailed. The formula is: If you don't understand again, add me QQ: 756406 10, and I will teach you. F = front, front B = back, back R = right, right L = left, left U = top, top D = bottom, for example, F stands for 90 clockwise, F' stands for 90 counterclockwise, and R2 stands for right 180. It's that simple. You got it? Rubik's cube is not played on one side, but is completed layer by layer. So how do you play six sides? The process is actually the first layer, the second layer and the third layer! It's simple to say, but each layer has to undergo some rotation to form, which is a bit interesting. It can also be said to be like magic. When you finish a process, twisting other places will not affect the layer you finished before. Of course, there are certain formulas or oral decisions. Are you a little excited? Let's see how each layer is distorted. Step by step in detail: You can add me (Ao Yunhui's) QQ7564076 10 and I'll send you a file, or ask me in QQ and we'll discuss it together. I have a good knowledge of formulas. The first floor (if you already know this floor, please jump to the second floor) is very important! It can be said that if you have the ability to complete one side, you will have the ability to complete six sides! It's just a matter of method. It won't hurt too many brain cells. Of course, you might say, I can finish my six-year-old nephew. What I said hurt your brain cells a little. I ask you to finish it with uniform colors around you. Maybe you've played it before and haven't paid attention to it, but today you have to play it like this if you want to be a "master". Is it much more difficult? Guess what? Let's assume that your spelling side is yellow. First, spell it in any color, such as yellow with color in the middle. Then, use yellow, blue and other colors to spell on a corner block (find a red one). Then, make a central square with yellow and red. Then, do it in the same way. If there is a yellow piece on it but the color is wrong, replace it and find the right piece until it is put together into a circle. How's it going? Have you ever practiced unilateral? Ok, let's look at the second level: second level, in order to look at the pictures conveniently, you must first say some English symbols here, and other people's stations in the world are also marked like this, so if you learn these symbols, you will understand how to twist them when you see other people's foreign websites. Let's assume that the Rubik's Cube is still, so it is divided into six faces: front (f), back (b), left (l), right (r), upper (u) and lower (d). Front = Back = Left = Right = Up = Down = Down, in which all the above are rotated clockwise, that is, 99 degrees. This means rotating 90 degrees counterclockwise. If you add a 2, it means turning twice, which means turning 180 degrees. In fact, after turning 180 degrees, the result is the same whether turning 180 degrees clockwise or counterclockwise. So sometimes you can choose whether to turn clockwise 180 degrees or clockwise according to your convenient direction. If you finish a line, turn the Rubik's cube upside down, with that side at the bottom and twist the color to the middle. You will find that there are probably two situations: Scheme 1: U R U' R' U' F' U F Scheme 2: (In fact, it is the same as above, but in the opposite direction) The principle of U L U U F' is decisive: one step away from the purpose, remove the next step and put it back. But if you encounter such a situation, you just need to change it in one of the above ways, and then change it into the shape above and do it again. Of course, if you are a person who is very interested in learning, you can directly solve this problem by memorizing the following long formula: f2u2r' f2rufu' fok? Then we will enter the third floor. There are three situations on the third floor: our current goal is: crossing! We call it point, line and solution for short. You just need to remember one formula! R' u' f' u 'f r If the cross has appeared, let's adjust it to the center color first. Of course, it may not be successful at the first time, and it may be necessary to change places. The formula for changing the position is very simple. This formula is to exchange the left edge and the front edge. RUR is very good. Your cross is centered on all sides. The next step is to change the angle. At this time, another formula is used, L 'rur' u 'lulu' r 'l 'ru 'lur' u 'l 'ul. Now is the most exciting moment, the last moment! Please keep a cool head! L' rur' u' lulu' r' turns the whole Rubik's Cube into a U, and then into L' ru' lulu' u' l' ul. What if it's not finished? Don't move, turn the Rubik's cube into a U-shape, and continue the previous steps! Turn the whole Rubik's Cube into a U, and then make an L. I'm sure it will work this time!
